Proportional Directional Valve 4WRZE10E85-7X/6EG24ETK31/A1D3M - Bosch Rexroth R900954568

A forging press expects short reversing times at full flow from its main valve. The 4WRZE10E85-7X/6EG24ETK31/A1D3M supplies 85 l/min nominal flow through spool symbol E, works up to 315 bar operating pressure and needs no dedicated pilot lines thanks to internal pilot oil supply and internal return.

Benefits

• Spool symbol E with three switching positions and 85 l/min nominal flow.
• Internal pilot oil supply and internal pilot oil return inside the valve body.
• Maximum operating pressure 315 bar, maximum flow 170 l/min.
• On-board electronics on 24 VDC, analog ±10 V command value through a 7-pole connector (6 + PE).
• Weight 8.37 kg, NBR seals, HL hydraulic fluid.

Applications

Forging presses, punching presses, scrap shears and baling presses reverse between advance and return in quick succession. The four working ports follow port pattern ISO 4401-05-05-0-05 of size 10. Main spool feedback happens inside the valve, the higher level controller only sets the command value.

Manufacturer

Bosch Rexroth lists the valve under R900954568. Type code 4WRZE10E85-7X/6EG24ETK31/A1D3M is decoded in datasheet RE 29115, which also holds characteristic curves and the port pattern, RE 07600-B adds the fluid data.
